编写一个程序,对输入的4个整数,求出其中的最大值和最小值,请使用C#编写。。。

static void Main(string[] args)
{
decimal max1,min2,number3;
Console.WriteLine("Please input 4 number:");
Console.WriteLine("请输入第一个数:");
number3= decimal.Parse(Console.ReadLine());
max1 = min2 = number3;
Console.WriteLine("请输入第二个数:");
number3 = decimal.Parse(Console.ReadLine());
if(number3 > max1 ) max1 = number3;
if(number3 < min2 ) min2 = number3;

Console.WriteLine("请输入第三个数:");
number3= decimal.Parse(Console.ReadLine());
if(number3 > max1 ) max1 = number3;
if(number3 < min2 ) min2 = number3;

Console.WriteLine("请输入第四个数:");
number3 = decimal.Parse(Console.ReadLine());
if(number3 > max1 ) max1 = number3;
if(number3 < min2 ) min2 = number3;

Console.WriteLine("最大值:" + max1.tostring());

Console.WriteLine("最小值:"+ min1.tostring());
}

}

{

{

}

for (int j = 0; j < line; j++)
{
for (int i = 0; i < row ; i++)
{

}
}
return temp;

}
public static void show(int[] temp)
{
for (int i = 0; i < temp.Length ; i++)
{
Console.Write(temp[i] + " ");
}
Console.WriteLine();

}
Console.WriteLine();

}
public static void wline()
{
Console.WriteLine("-------------------------------------------------------------------");
}
